Does the clinical and radiologic outcomes following total knee arthroplasty using a new design cobalt-chrome tibial plate or predecessor different?
Article in Knee surgery & related research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study aimed to compare clinical and radiographic outcomes for a new tibial component (Attune S +) and the previous design (Attune S) in total knee arthroplasty (TKA) patients using ATTUNE® posterior stabilized (PS) prosthesis and also assessed related factors for the development of tibial radiolucent line(RLL).
methodsThis retrospective study included 362 knees (179 Attune S, 183 Attune S +) with an average 4 years (range, 2-8) follow-up. Clinical outcomes, radiologic parameters and the incidence of RLL around the tibial component were compared through the serial assessment. For the subgroup analysis, radiologic parameters were compared between patients with and without RLL.
resultsThere was no significant difference in terms of clinical outcomes and radiologic parameters between two designs. The incidence of RLL was not different through the serial follow-up (P > 0.05). In the subgroup analysis, the preoperative medial proximal tibial angle (83.7° versus 85.0°, P = 0.01) was smaller and preoperative hip-knee-ankle angle (169.1° versus 171.8°, P = 0.01) has more varus in the group with RLL than those without.
conclusionsThe clinical and radiologic outcomes including the incidence of tibial RLL between new design and predecessor were not significantly different at average 4 years follow-up. The development of tibial RLL was associated with preoperative varus deformity of tibia and lower limb alignment.
